Sewage treatment reaction tank and purification system for sewage treatment

Abstract

The invention relates to a purification system for sewage treatment. The purification system comprises a first sewage treatment reaction tank, a second sewage treatment reaction tank, a quick filtering tank, a carbon filtering tank and a nano-sewage clarifying tank, wherein a clean water accommodation tank of the first sewage treatment reaction tank is communicated with a tank body of the second sewage treatment reaction tank through a pipeline with a water pump, a clean water accommodation tank of the second sewage treatment reaction tank is communicated with a liquid inlet of the quick filtering tank, and a filter liquid outlet of the filtering tank is communicated with a liquid inlet of the carbon filtering tank; a lower sludge outlet of the tank body of the first sewage treatment reaction tank and a lower sludge outlet of the tank body of the second sewage treatment reaction tank are respectively communicated with the nano-sewage clarifying tank. The purification system has the advantages that the sewage and wastewater can be separately treated, the limitation by the address selection of a sewage treatment factory is avoided, the cost is low, the separation effect is good, andthe good treatment effect is guaranteed; the treatment and purification functions are integrated, the pollution-free treatment is not simply performed on the sewage and wastewater, and the treated sewage and wastewater can be recycled as mixed water, so as to conserve the high-quality running water.

Description

technical field [0001] The invention relates to a sewage treatment reaction pool and a sewage treatment-purification system, in particular to a sewage treatment-purification system which can easily realize the decentralized treatment of sewage, and belongs to the field of environmental protection equipment. Background technique [0002] At present, sewage or wastewater treatment mainly relies on sewage treatment plants. The location of sewage treatment plants is relatively fixed. Sewage or wastewater in a certain area must be transported to sewage treatment plants through pipeline transportation and other channels to complete the treatment. Due to the source of sewage or wastewater The geographical location of the sewage treatment plant is scattered or lower than the height of the geographical location of the sewage treatment plant. It is quite limited to collect the sewage or wastewater within the jurisdiction of a certain sewage treatment plant. For example, market towns t...

Problems solved by technology

For example, market towns that have not built sewage treatment plants so far, produce common heavy metal ions or common toxic and harmful ions (such as cyanide CN - , Fluorine F - , Arsenic As 3+ 、As 5+ ) of scattered enterprises, landscape lakes that need to be treated to replace water sources, and aquaculture enterprises to produce wastewater, it is difficult to collect and treat all the sewage or wastewater from the above-mentioned sources due to the geographical location of the above-mentioned sources of sewage or wastewater; in addition, Landscape lakes generally have no idle land to build sewage treatment plants, and aquaculture enterprises may not be able to build sewage treatment plants due to construction investment and other reasons, resulting in sewage not being treated in time, or needing to use a large amount of high-quality tap water to replace polluted landscape lakes source of water

In addition, most of the existing sewage treatment equipment that adopts the sequencing batch activated sludge process to treat sewage currently use electromechanical rocker, sleeve, siphon, rotary and buoy type decanting devices, which need to be configured to collect water. Water device, connection device, transmission device or even some special drainage device, the structure of this kind of decanting device is relatively complicated and the cost is high
